In order to study the detailed matching mechanism among the pulse detonation combustor,the turbine and the compressor,the pulse detonation turbine engine test system, which is mainly composed of the pulse detonation combustor,the turbocharger,the lubrication system,the engine monitoring and control system and so on,is established.The pulse detona-tion turbine engine principle experiment is carried out,and it is firstly succeed that the turbine is driven by the pulse detonation combustor and the compressor compresses air supplying for the pulse detonation combustor.The test results show that the pulse detonation turbine engine can stably work at self-suction mode durably,and the pulse detonation chamber,the turbine and the compressor match well,which verifies that using the pulse detonation combustor to alter the con-ventional isobaric combustion chamber is feasible.
